MEANS FOR HOLDING ELECTRODES USED IN SOLDERING AND DEPOSITING METALS BY- TEE ELECTRIC ABC.

Application filed February 25, 1920. Serial No. 861,189.

To all whom it may concern:

Be it known that I, Ennasr I'IENRY corms, subject of the King sidin a; 18 and 20.Church Street, Islington, ndon, England, have invented new and useful Improvements in Means for Holding Electrodes Used in Soldering and Depositing Metals by the Electric Arc, of which the following is a specification.

This invention has for its object improved means for holding electrodes usedin soldering and depositing by the electric arc of the type in which an insulated handle or hand grip is fixed upon a metal stem'capable of carr ing the electric current, the upper end of tlie stem being provided with means for gripping the end of the metal-,electrdde and the lowerend being provided with a suitable joint or connection by which the current cable may be attached and electrically con-. nected to the stem.

According to this invention the stem is provided with a gripping device in the nature of 'a drill chick with compressible jaws arranged in a conical housing, and the handle or hand grip; is provided with a simple form of switch by means of which the current may device when fitting a new electrode or when the holder is not 1n use.

The accompanying drawing illustrates aholderconstructed according to the invenrip formedof aninsulating material, and g is a metal stem fixed to the handle a and electrically con-' nected'to one part c of a switch suitably secured in the'handle'. The other part (1 of the switch is secured within the opposite end of the handle a and is provided with a screw c ,to grip the electric cable f and provide electrical connection with the part d of the of Great Britain, 're-' electrical connection with be cut oil from the gripping vstem consisting of conical switch. The handle a is provided with an insulated switch lever g pivoted to the handle at h and provided with a throw-ofi' spring 6; theswitch lever g is also provided with a metal blade or bridge k adapted to electrically connect the two parts 0 and d of the switch when the handle a and lever g are gripped in the hand. The upper end of the stem 6 isprovided with a gripping device which comprises conical gripping jaws Z mounted within aconical housing m and a hand. screw n to thrust forward the jaws Z and cause them to-gri the metal wire or rod of the electrode 0. 'fh device is set at a suitable to the-stem.

I claim o 1. An electrode holder comprising a metal stem a chuck on said stem, an insulated handle fixed on said stem, 9.- switch contact electrically connected to said stem and located within the handle, a second switch contact-located in the handle and capable of a flexible cable, insulated switcl. connecting both angle with. respect a switch blade fixed to an lever capable of electrically contacts of said switch, a spring holding the switch blade away from the swltch contacts, and means connecting the holder to an electric cable, as set forth.

2. An electrode holder comprising a metal stem, said stem, a chuck on the other end of said gripping jaws mounted within a conical housing and operated by a hand screw, av hand 0 rated contact making device in the hand e, and means electrically connectin 'the holder to an electric cable, as set forth.

In testimony whereof I have signed my name to this s ecification. F
